SZMMBZ5245BLT1G from onsemi, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ANODE | passive | Anode terminal of the Zener diode, assigned to pin 1 by the Style 8 SOT-23 pinout. |
| 2 | NC | unconnected | No connection; the datasheet pinout designates this pin as NO CONNECTION. |
| 3 | CATHODE | passive | Cathode terminal of the Zener diode, identified on the package by the polarity band. |
